Issues Applying Custom Pinmux DTBO on Jetson Orin Nano (L4T 35.3.1 / JetPack 5.1.1)

fjserrano · July 30, 2025, 1:46pm

I’m porting a custom carrier board for the Jetson Orin Nano and need to modify the pinmux and GPIO defaults. I followed the “Generating the Pinmux dtsi Files” procedure in the Orin NX/Nano Developer Guide and built the three DT files (pinmux.dtsi, gpio-default.dtsi, padvoltage-default.dtsi) from the NVIDIA spreadsheet and after all the process and flashing the module the result is the same if i don’t use the files generated by spreadsheet.

jtop

L4T 35.3.1, JetPack 5.1.1, Ubuntu 20.04, Orin Nano Module (P3767-0003).

Setup

Placed Orin-embedded_ia-gpio-default.dtsi in Linux_for_Tegra/bootloader/

Placed Orin-embedded_ia-pinmux.dtsi and Orin-embedded_ia-padvoltage-default.dtsi in Linux_for_Tegra/bootloader/t186ref/BCT/

Created jetson-orin-nano-devkit-custom.conf pointing to those three files as GPIOINT_CONFIG, PINMUX_CONFIG, and PMC_CONFIG.

Flashing Overlay Only

I do not want to overwrite my existing rootfs; I only want to regenerate and flash the pinmux overlays to the module. I ran:

sudo ./tools/kernel_flash/l4t_initrd_flash.sh
-p “–no-systemimg -c bootloader/t186ref/cfg/flash_t234_qspi.xml”
–network usb0
jetson-orin-nano-devkit-custom internal
| tee flash_jetson_orin_embedded_ia.log

The log reports success and indicates it compiled everything without errors.

flash_jetson_orin_embedded_ia.log (205.9 KB)

Verifying Boot Behavior

I temporarily removed all files from /boot/extlinux/ to force the SoC to load the UEFI DTB with overlays by default (per UEFI boot flow docs).

imagen

After reboot there are no pinmux or GPIO changes in Linux and the /sys/kernel/debug/gpio still show defaults.

Attempting Full Image Generation

I also tried generating the complete set of images (including extlinux.conf and DTB) without flashing:

sudo ./flash.sh
–no-flash
-c bootloader/t186ref/cfg/flash_t234_qspi.xml
jetson-orin-nano-devkit-custom internal
| tee flash_noflash.log

flash_noflash.log (8.7 KB)

I extracted the generated /boot/extlinux/extlinux.conf, the new DTB, and its accompanying DTBO. However, the system still does not pick up my overlay.

My Questions:

Critical Pinmux Question:

What am I missing to actually make my custom pin configuration take effect in Linux? This is my primary concern.

Debugging Tips:

Any suggestions on logging or tools (e.g. using cboot commands, tegrahost, etc.) to verify at which stage the custom BCT overlays are applied?

Overlay Application:

How can I confirm which DTB (and overlays) UEFI is actually loading at boot?
What else do I need to modify so that my custom DTBO gets applied automatically?

Flash Scripts:

Is there a recommended way to force l4t_initrd_flash.sh or flash.sh to rebuild only the DTBOs and EXTLINUX entries, without touching system.img?
Are there any pitfalls in my custom .conf that would prevent the overlays from being packaged?

I’ll attach relevant snippets of:

jetson-orin-nano-devkit-custom.conf and gpio pinmux dtsi config
jetson_pin_config_embedded_ia.zip (9.0 KB)

extlinux.conf and dtbo generated on image

extlinux_and_dtbo.zip (55.2 KB)

Thanks in advance for any guidance!

Hi fjserrano,

You don’t need to configure GPIOINT_CONFIG, which is used for gpio interrupt configuration.
Please just confirm Orin-embedded_ia-gpio-default.dtsi is included in Orin-embedded_ia-pinmux.dtsi

You can simply run the following command to flash QSPI only to apply the change.

$ sudo ./flash.sh -c bootloader/t186ref/cfg/flash_t234_qspi.xml jetson-orin-nano-devkit-custom internal

Please note that pinmux/gpio dtsi are loaded in early boot stage(MB1) rather than in kernel.

For DTB relates issue, please open another topic to discuss in details.
Basically, it should follow what FDT and OVERLAYS entry specified in extlinux.conf.

You can simply run the following command on your board to capture current device tree settings.

$ sudo dtc -I fs -O dts -o extracted_proc.dts /proc/device-tree

Hi again,

Thanks for the pointers, here’s what I’ve done since your last message:

Removed GPIOINT_CONFIG
I removed the GPIOINT_CONFIG line from my jetson-orin-nano-devkit-custom.conf, so now it only sets:

jetson-orin-nano-devkit-custom.conf

source "${LDK_DIR}/p3767.conf.common";

# update_flash_args_common:
update_flash_args_common()
{
	local emcfuse_bin="${1}";
	local emcpredefvalue="${2}"

	if [ ${EMC_OPT_DISABLE_FUSE_OVERRIDE} -eq 0 ]; then
		return;
	fi

	# EMCFUSE_VALUE can be passed by user
	emc_opt_disable_fuse="${DEFAULT_EMC_FUSE}";

	if [ -n "${emcpredefvalue}" ]; then
		emc_opt_disable_fuse="${emcpredefvalue}";
	elif [ -f "${emcfuse_bin}" ]; then
		emc_opt_disable_fuse=`xxd -ps "${emcfuse_bin}" | xxd -p -r | grep "OptEmcDisable" | awk '{print $2}' | sed 's/.*\(.\)/\1/'`;
	fi

	echo "emc_opt_disable_fuse:(${emc_opt_disable_fuse})"

	if [ "${board_sku}" = "0000" ] || [ "${board_sku}" = "0002" ]; then
		# use default DTB and CFG files except for TS1 & EB1 revisions
		if [ "${board_FAB}" = "TS1" ] || [ "${board_FAB}" = "EB1" ]; then
			PINMUX_CONFIG="tegra234-mb1-bct-pinmux-p3767-dp-a01.dtsi";

			BPFDTB_FILE="tegra234-bpmp-3767-0000-a00-3509-a02.dtb";
		fi
	elif [ "${board_sku}" = "0001" ]; then
		BPFDTB_FILE="tegra234-bpmp-3767-0001-3509-a02.dtb";
		DTB_FILE="tegra234-p3767-0001-p3768-0000-a0.dtb";
	elif [ "${board_sku}" = "0003" ] || [ "${board_sku}" = "0005" ]; then
		BPFDTB_FILE="tegra234-bpmp-3767-0003-3509-a02.dtb";
		DTB_FILE="tegra234-p3767-0003-p3768-0000-a0.dtb";
	elif [ "${board_sku}" = "0004" ]; then
		BPFDTB_FILE="tegra234-bpmp-3767-0004-3509-a02.dtb";
		DTB_FILE="tegra234-p3767-0004-p3768-0000-a0.dtb";
	fi

	TBCDTB_FILE="${DTB_FILE}";
}

# update_flash_args:
update_flash_args()
{
	# All updates should go into update_flash_args_common to allow
	# for other files to include this file and override variables.
	update_flash_args_common
}

# update_emmc_cfg_for_bup:
update_emmc_cfg_for_bup()
{
	local bup_type="${1}"

	if [ "${bup_blob}" -ne 0 ] && [ "${bup_type}" == "bl" ]; then
		EMMC_CFG="flash_t234_qspi.xml";
	fi
}

DEFAULT_EMC_FUSE="0";
#PINMUX_CONFIG="tegra234-mb1-bct-pinmux-p3767-dp-a03.dtsi";
#PMC_CONFIG="tegra234-mb1-bct-padvoltage-p3767-dp-a03.dtsi";
#GPIOINT_CONFIG="Orin-embedded_ia-gpio-default.dtsi";
PINMUX_CONFIG="Orin-embedded_ia-pinmux.dtsi";
PMC_CONFIG="Orin-embedded_ia-padvoltage-default.dtsi";
BPFDTB_FILE="tegra234-bpmp-3767-0000-a02-3509-a02.dtb";
DTB_FILE="tegra234-p3767-0000-p3768-0000-a0.dtb";
TBCDTB_FILE="${DTB_FILE}";
EMMC_CFG="flash_t234_qspi_sd.xml";

If you grep the top of Orin-embedded_ia-pinmux.dtsi, you’ll see it pulls in my gpio-default dtsi, e.g.:

/dts-v1/;
#include "pinctrl-tegra.h"

#include "./Orin-embedded_ia-gpio-default.dtsi"
/ {
	pinmux@2430000 {
		pinctrl-names = "default", "drive", "unused";
		pinctrl-0 = <&pinmux_default>;
		pinctrl-1 = <&drive_default>;
		pinctrl-2 = <&pinmux_unused_lowpower>;
...
...

Flashed QSPI
I then ran exactly as you recommended:

sudo ./flash.sh -c bootloader/t186ref/cfg/flash_t234_qspi.xml jetson-orin-nano-devkit-custom internal | tee ../flash_jetson_orin_embedded_ia_20250731_1.log

flash_jetson_orin_embedded_ia_20250731_1.log (86.3 KB)

I think viewing log all is ok named my files of pinmux on log

Verified in Linux

sudo dtc -I fs -O dts -o /tmp/extracted_proc.dts /proc/device-tree

Attach the dts extracted: extracted_proc.zip (62.1 KB)

Unfortunately it still matches the stock pinmux and GPIO defaults—none of my custom settings appear, and I still don’t see my SPI/I²C nodes or alternate‐function pin-configs in /sys/kernel/debug/gpio or DTS from /proc/device-tree

/sys/kernel/debug/gpio

Any idea how I can make my custom pin configuration on boot? According to the logs everything flashes correctly, but Linux still comes up with the stock pin settings. Please help!

Thanks in advance.

It is expected since the pinmux/gpio dtsi you generated are loaded in MB1 rather than in kernel so that there would be no change in kernel DTB.

You can simply use devmem command to check the PADCTL register to verify if your change has been applied correctly.
Or you can run the following command to check current pinmux configuration.

# cat /sys/kernel/debug/pinctrl/2430000.pinmux/pinconf-groups

I’ve just checked the active pinmux state in Linux and it still doesn’t match my custom DTIs. I ran:

cat /sys/kernel/debug/pinctrl/2430000.pinmux/pinconf-groups

pinconf-groups.log (39.3 KB)

But when I load spidev in user space, it still presents as spi2 (the stock SPI2 pins), which shouldn’t even exist on my board according to my spreadsheet-generated pinmux DTIs. In my custom .dtsi I explicitly moved SPI2 pins elsewhere and re-assigned PCC00–PCC03 as GPIO outputs, yet neither the kernel device tree nor the padctl registers reflect any of those changes.

Maybe the spreadsheet is not generating correctly de dtsi??

What else can I check or modify so that my MB1‐stage pinmux overlay actually takes effect? Is there a step I’m still missing to push the updated pin configuration all the way through UEFI into the running kernel?

Thank you for any guidance!

From the pinconf-groups result you shared, it has been configured as rsvd1 in func.

9 (spi2_sck_pcc0): 
	pull=0
	tristate=0
	enable-input=0
	open-drain=1
	io-reset=1
	rcv-sel=1
	io-hv=1
	loopback=0
	schmitt=1
	pull-down-strength=0
	pull-up-strength=0
	drive-type=0
	func=rsvd1
	pad-power=0

The /dev/spidev2.0 and /dev/spidev2.1 are produced since you load the spidev driver and they are enabled in device tree.
Please also try to disable them in spi@c260000 node of device tree.
You can also check the dmesg for details.

Hi KevinFFF,

Thanks for the suggestion—here’s what I’m seeing when I try to disable SPI2 in the device tree:

$ cat /proc/device-tree/spi@c260000/status
disabled

$ sudo modprobe spidev
$ cat /proc/device-tree/spi@c260000/status
disabled

And yet /dev/spidev2.0 and /dev/spidev2.1 still appear as soon as I load the spidev driver:

$ ls -l /dev/spidev*
crw-rw---- 1 root gpio 153, 0 Jun 17 22:39 /dev/spidev0.0
crw-rw---- 1 root gpio 153, 1 Jun 17 22:39 /dev/spidev0.1
crw-rw---- 1 root gpio 153, 2 Jun 17 22:39 /dev/spidev2.0
crw-rw---- 1 root gpio 153, 3 Jun 17 22:39 /dev/spidev2.1

So it looks like SPI2’s node is truly “disabled” in the DT, but the driver still creates its /dev entries. Disabling that node doesn’t prevent spidev from claiming it.

Meanwhile, my SPI1 pinmux fragment is configured like this in the spreadsheet-generated DTI:

spi1_sck_pz3 {
nvidia,pins = “spi1_sck_pz3”;
nvidia,function = “spi1”;
…
};
same for spi1_miso_pz4, spi1_mosi_pz5, spi1_cs[01]_pz[67]

Yet after flashing and boot, no /dev/spidev1.* appear.

My questions now are:

How can I prevent the spidev driver from creating /dev/spidev2.* if its DT node is status = “disabled”?
What step is still missing so that SPI1 actually becomes visible when load spidev module?
Do I need to supply a kernel DT overlay (.dtbo) to explicitly disable SPI2 and enable SPI1, and if so, how do I reference that in extlinux.conf?

I appreciate any pointers on how to make SPI1 use the pins I defined and stop SPI2 from cluttering my device list. Thanks!

KevinFFF · August 11, 2025, 7:38am

I suspect /dev/spidev2.* are created by SPI3(spi@3230000) rather than SPI2(spi@c260000).
Please share the full dmesg after you run sudo modprobe spidev for further check.

You can simply add OVERLAYS option in /boot/extlinux/extlinux.conf for this use case.

fjserrano · August 12, 2025, 9:30am

Hi @KevinFFF,

Thanks for the pointers. I tried to collect the evidence you asked for.

dmesg after (re)loading spidev
I enabled dynamic debug for spidev and spi-tegra114, reloaded the module, and captured dmesg. There are no new lines related to spidev or the SPI core when I run modprobe spidev (even with dynamic debug on). I can attach the full log if needed.

Which SPI controllers are enabled vs. disabled in the live DT

/proc/device-tree/spi@3210000/status -> okay
/proc/device-tree/spi@3230000/status -> okay
/proc/device-tree/spi@3300000/status -> disabled
/proc/device-tree/spi@c260000/status -> disabled

Which controller creates each /dev/spidevX.Y

/sys/class/spidev/spidev0.0 -> /sys/devices/platform/3210000.spi/spi_master/spi0/spi0.0
/sys/class/spidev/spidev0.1 -> /sys/devices/platform/3210000.spi/spi_master/spi0/spi0.1
/sys/class/spidev/spidev2.0 -> /sys/devices/platform/3230000.spi/spi_master/spi2/spi2.0
/sys/class/spidev/spidev2.1 -> /sys/devices/platform/3230000.spi/spi_master/spi2/spi2.1

This is the info I have on the system.

My questions are the next:

1) How do the spreadsheet “SPIx” names map to Linux controllers and /dev?
Could you confirm the mapping between the pinmux spreadsheet’s SPI1/SPI2/… and the Linux DT nodes and the name on the spreadsheet because i have 2 names on same line:

spi@3210000
spi@3230000
spi@3300000
spi@c260000

I specifically need to use the SPI routed to SOM pins 89-91-93-95-97 and a second SPI on 104-106-108-110 (those are the module pin numbers). Which controller nodes do those correspond to?

imagen
imagen

2) Overlay to enable the correct SPI(s) and hide the others

If the pinmux (MB1) configuration is correct, my understanding is I still need a kernel DT overlay to enable the intended SPI controller(s) in Linux. Could you help me create such an overlay, at least one working example, so I can understand the right way to define it and enable it on the /boot/extlinux/extlinux.conf file.

Thanks for all of your support.

KevinFFF · August 13, 2025, 9:53am

Maybe you can refer to their mapping in https://elinux.org/Jetson/L4T/peripheral/#Mapping.

Please add the FDT entry in /boot/extlinux/extlinux.conf to specify the DTB in use.
e.g. FDT /boot/dtb/kernel_tegra234-p3768-0000+p3767-0005-nv.dtb

You can simply decompile this dtb to dts and update the device tree manually

fjserrano · August 16, 2025, 10:43am

Hi @KevinFFF,

Thanks, the SPIx mapping link is exactly what I needed.

My plan is:

Use the DTB that the script flahsing creating the image for QSPI, decompile it,
Set spi@c260000 to status = "okay" and set spi@3230000 to status = "disabled",
Rebuild the DTS to DTB and point /boot/extlinux/extlinux.conf to it via FDT ... (and/or OVERLAYS ...) to validate it boots with the change.
Validate on kernel that spidev1.x is up and spidev2.x is down.

I’m out of the office this week; I’ll try this late next week and report back.
If anything in that plan looks off, please let me know.

Thanks again!

KevinFFF · August 18, 2025, 7:53am

Okay, it seems that you want to enable SPI1(spi@3210000) and SPI2(spi@c260000) but disable SPI3(spi@3230000).
The workflow looks good to me.
Please update the DTB file and you can check the current settings under /proc/device-tree.

fjserrano · August 23, 2025, 3:28pm

Hi @KevinFFF,

I tried to switch the system to a DTB in /boot via extlinux.conf, but it looks like UEFI isn’t parsing extlinux at all.

What I did

/boot/extlinux/extlinux.conf (active label):


TIMEOUT 30
DEFAULT primary

MENU TITLE L4T boot options

LABEL primary
      MENU LABEL primary kernel
      LINUX /boot/Image
      INITRD /boot/initrd
      FDT /boot/dtb/kernel_tegra234-p3767-0000-p3768-0000-a0.dtb
#     FDTDIR /boot/dtb
      APPEND testflag=hello ${cbootargs} extdtb=TEST_P3767_A0

I use testflag and extdtb to validate after restart if is loading this option.

After reboot:

$ cat /proc/cmdline
root=PARTUUID=9aede23d-88d0-473a-8631-41806a727110 rw rootwait rootfstype=ext4 mminit_loglevel=4 console=ttyTCU0,115200 console=ttyAMA0,115200 firmware_class.path=/etc/firmware fbcon=map:0 net.ifnames=0

$ cat /proc/cmdline | tr ' ' '\n' | grep -E 'testflag=|extdtb='
# (no output)

I attached the dmesg log after reboot for help to you why is not loading extlinux.conf. dmesg.log (59.6 KB)

What’s the recommended way on Orin Nano (R35.3.1) to force the system to boot via L4TLauncher so that /boot/extlinux/extlinux.conf is honored?

Once I can get extlinux.conf to apply, I’ll proceed with the DTB/OVERLAYS workflow you suggested (enable spi@c260000, disable spi@3230000, etc.).

Thanks for the guidance!

KevinFFF · August 25, 2025, 9:01am

It will use the DTB specified in FDT.

Could you revert it to the original and just append your string at the end?

It seems the original kernel command line looks like the following.

[    0.000000] Kernel command line: root=PARTUUID=9aede23d-88d0-473a-8631-41806a727110 rw rootwait rootfstype=ext4 mminit_loglevel=4 console=ttyTCU0,115200 console=ttyAMA0,115200 firmware_class.path=/etc/firmware fbcon=map:0 net.ifnames=0

fjserrano · August 29, 2025, 9:04am

Hi @KevinFFF,

Thanks for the guidance. I followed your request and appended the string at the end, as shown below:

TIMEOUT 30
DEFAULT primary

MENU TITLE L4T boot options

LABEL primary
MENU LABEL primary kernel
LINUX /boot/Image
INITRD /boot/initrd
FDT /boot/dtb/kernel_tegra234-p3767-0000-p3768-0000-a0.dtb
APPEND ${cbootargs} extdtb=TEST_P3767_A0 testflag=hello

I’m attaching the boot dmesg nothing changes; it looks like the system is ignoring the extlinux.conf entry.

boot_dmesg.txt (60.4 KB)

I also connected to the debug UART. The last line I see is:

boot_log.txt (7.0 KB)

[0000.703] I> Task: Pinmux init (0x5001397d)

After this, there’s no further output. This is confusing because in my pinmux configuration I kept the debug UART at its default, so it should keep printing.

I’m trying to read the bootloader logs to understand the boot flow, but since the output stops there, I can’t see what’s happening. Any pointers on why extlinux.conf seems to be ignored and why the UART output stops right after pinmux init would be appreciated.

Best Regards.

KevinFFF · September 1, 2025, 6:24am

It looks not like the default configuration, could you revert it?
There’s no cboot in R35.3.1.

Is your current issue about pinmux device tree not applied or the attributes(extdtb=TEST_P3767_A0 testflag=hello) you added in extlinux.conf not reflected?

fjserrano · September 4, 2025, 3:58pm

Hi @KevinFFF,

I’ve reverted extlinux.conf to the default style.
My main goal is to confirm the spreadsheet pinmux is actually applied; right now it doesn’t seem to match at runtime.
I tried runtime DT overlays / setting FDT directly to avoid reflashing. On JP 5.1.1 (R35.3.1), is there any supported way to apply pinmux changes via FDT/OVERLAYS or configfs at runtime, or are pinmux changes only possible via MB1 (QSPI) BCT so reflashing is required?
Separately: even if pinmux must come from MB1, is it possible to load a kernel DT overlay (.dtbo) at OS boot (via OVERLAYS in extlinux.conf) to enable/disable kernel-visible nodes (e.g., SPI/I²C) while leaving MB1 pad settings as-is? If yes, what’s the recommended path on R35.3.1?

I’ll proceed with a QSPI-only reflash as you suggested and then verify with pinconf-groups. If there’s any MB1-specific step I should double-check, please let me know.

Best Regards.

You can simply run the following command before and after you made the change

//SPI2_SCK - PCC.00
$ sudo busybox devmem 0x0c302048

pinmux/gpio dtsi is included in MB1 BCT and they are loaded in early boot (MB1) so that you have to reflash to apply that change.
If you don’t want to reflash the board, you can add similar configuration to pinmux@2430000 node so that the pinctrl kernel driver will configure them during boot up.

You should able to configure the pinmux with both methods.
Please just run devmem command to check if your change has been taken effect.

Hi @KevinFFF,

I built my carrier to match the Orin Nano devkit SPI routing (same level-shifter, same pins). DT pinmux is set to spi3 on PY0..PY3, I load spidev, /dev/spidev2.0 appear, and the interrupt for 3230000.spi increments on each transfer:

sudo cat /proc/interrupts | grep spi

69: 14 0 0 0 0 0 GICv3 70 Level 3230000.spi

But on the logic analyzer there is no activity at all (no SCK/MOSI/CS). If I switch those pins to GPIO (Changing the Device tree and reflashing module) I can toggle them fine, so the wiring is OK, the issue only happens in SPI mode but the func=spi3 is enable correctly on /sys/kernel/debug/pinctrl/2430000.pinmux/pinconf-groups.

Anything else I should check on R35.3.1 to get SPI3 to actually drive pins?

I can’t test directly example on elinux.org Making sure you're not a bot! because on my R35.3.1 I can’t load from extlinux.conf that the python script does.

In this point I only need to make SPI transfer on spidev2.0.

Thanks for your support.

Best Regards.

Do you have the devkit to verify for the similar steps?

If you have the similar design as the devkit, you should be able to use jetson-io.py tool to enable SPI functions.

I’m not clear about why you said that you can not load extlinux.conf.
Please provide your /boot/extlinux/extlinux.conf for further check.

Please also share the result of the following commands to read the pinmux register for SPI3.

$ sudo busybox devmem 0x0243d000 //SPI3_MISO
$ sudo busybox devmem 0x0243d048 //SPI3_MOSI
$ sudo busybox devmem 0x0243d030 //SPI3_SCK
$ sudo busybox devmem 0x0243d010 //SPI3_CS0
$ sudo busybox devmem 0x0243d020 //SPI3_CS1
